Emil recieved his PhD in physics from NTNU september 2019 with a background in transmission electron microscopy (TEM) of deformed aluminium alloys. His earlier masters degree is also from NTNU, where he studied epitaxially grown LaFeO3 thin films on (111) terminated SrTiO3 substrates. Today, Emil is working as a senior engineer at the NORTEM laboratories at the Department of Physics, where he trains new users, serves projects as a for-hire operator, maintains and develops the TEM infrastructure, investigates new TEM methods and applications, and works with the strategic development of the infrastructure.
